To all whom it may concern Be it known t at I, Go'rTLrEB GHRIsTOF .ZIMMERMANN, a citizen of the German Emr the art to which it appertains to make and fruit which is cut into pieces is ment in its own sap for treatment the other advantage is, obtained the heretofore use the same.

My invention relates to a process for making a kola preparation for use as food.

It has already been proposed to make a longlasting preparation of the well known kola fruit by roasting the fresh (not yet dried) kernel of the fruit that may have been kept in store for a shorter or longer time, in order to remove its bitter taste that makes it nauseating to civilized people. Apart from the fact thatthe purpose intended is not obtained by this roasting of the kola fruit, moreover a great part of the alkaloids, (caifein and a little theo-bromin) from the bound form into the free one, in'

which they are by far less valuable. In known preparations of kola the special qualities of the fresh kola fruit (namely, the stimulating and refreshing effect) are lost on account of the fact that the kola nuts were roasted.- In applicants process the roasting is entirely done away with; This conversion of the alkaloids from the bound form into the free one is prevented in the new process in whichthe fresh left to fer- By this some time.

that the fruit loses its disagreeable bitter taste due to the volatile oils, that are volatilized hereby.

In executing the kola fruits that may have been kept in store new process, 'the fresh for some time, if they do not lose their I freshness thereby,are at first cut into pieces and are in thiscondition .put into stores for 3-6 days, depending on the condition of the fruits, and left to ferment in their own sap. The product obtained is then subjected in known manner to a roasting process at a temperature of about 180 200 degrees C. for so long a time that the small kola pieces are completely roasted. The preparation obtained in this manner shows a mild, aromatic flavor and in its effect differs in no manner from the fresh fruit; but contrary to the fresh fruit it lasts without special treatment for years. r i

The kola preparation may be used in any convenient manner; for instance it may be boiled in hot water and the liquor obtained may be mixed with sugar and. thickened; but of course the kola extract, gained by boiling in water might also be used immediately as a beverage in a similar manner to coffee, tea or the like.

I claim:

A process for making a kola preparation consisting in cutting thev fresh fruits to pieces, leaving them to ferment and then roasting the product obtained at a temperature of 180-200 v In testimony whereof I afiix my signature, in presence of two witnesses.
